[1～2月]做好植株的防寒保苗,室温不低于10℃,严格控制浇水,每周浇水1次,盆土不宜过湿。摆放阳光充足的场所。[3月]播种繁殖,常用室内盆播,发芽适温为18℃～24℃。出苗后,每周浇水2次,每2周施薄肥1次。[4月]苗期浇水过多,会引起茎叶徒长。每2周施薄肥1次。此时,开始露地播种,种子要求新鲜、饱满,发芽、成苗率高。[5月]苗具3片～4片叶时可盆栽,移栽时多带土。随着苗株长高,及时做好摘心,可多萌发分枝,使茎叶丰满、开花多。每周浇水2次,每2周施肥1次。扦插繁殖,剪取嫩枝,长
[1 ~ 2 months] Plant cold-proof seedlings, room temperature not less than 10 ℃, strict control of watering, watering once a week, basin soil should not be too wet. Place ample sunshine. [March] Sowing and breeding, commonly used indoor pot planting, germination suitable temperature is 18 ℃ ~ 24 ℃. After emergence, watered 2 times a week, every 2 weeks Shi thin 1 times. [April] Too much watering at the seedling stage can cause stems and leaves to grow. Fertilize every 2 weeks. At this point, began to open seeding, the seeds require fresh, full, germination, high seedling rate. [May] Seedlings with 3 ~ 4 leaves when potted, with more soil when transplanted. With the seedlings grow high, timely topping, can be more germination of branches, the stems and leaves plump, more flowering. Watering twice a week, fertilizing once every 2 weeks. Cutting propagation, cutting shoots, long
